America has always treated the Arabs as a dumb, inferior race which are famous for disagreeing amongst their own nations.
America needs the Arab oil at whatever cost. The only way to achieve this , by supplying the Arabs with defence armaments. Once this armament has reached the limit, then America is quite well known to create a scare mongering technique, whereas further arms are needed or create a foe where these armamants can be used against.
Should this foe be insufficient to appease, then America will use its powers to create an invasion against that foe, by doing so America has the possibilty of using their stockpile of arsenal against that nation.
What has America achieved by this exercise is, to dispose of all the obsolete hardware that cannot be otherwise disposed of in their own country. Furthermore, they are well known to charge the cost of such arsenal to be paid by the country that they have protected.
In summary, United States gets the oil, gets paid for their armament and obtain further military orders just in case of any future foes that may emerge.
